Configuring IP Parameters for CESoPSN Bundles on CTP2000 Devices (CTPView)

The CTP software uses the IP parameters to create IP packets.

Before you begin:

Log in to the CTPView software at least at the Net_Admin level.
Connect the CTPView server to the CTP device for which you want to configure bundles.

To configure IP parameters for CESoPSN bundles using CTPView:

In the side pane, select Bundle > Configuration.
Run your mouse over the Display and Select an Existing Bundle bar.
In the table of bundles, select the bundle that you want to modify.
Under Bundle Options, configure the parameters described in Table 1, and click Click to Submit Bundle AND Port Changes.

Table 1: CESoPSN Bundle IP Parameter Settings on CTP2000 Devices in CTPView
Field	Function	Your Action
Bundle Description	Specifies identifying information about the bundle.	Type a description for the bundle.
State	Specifies whether the bundle is active or disabled.	Select DISABLED or ACTIVE. After the bundle is activated, the bundle transitions to RUNNING or InSYNC state.
Remote Address	Specifies the name and IP address of the remote CTP device.	In the first field, select the CTP device. In the second field, select an interface on the CTP device.
Packet Size	Specifies the size of IP packets that are created from data received at the port. The CTP software calculates a default packet size based on the number of time slots configured, the type of interface (T1 or E1), and the type of signaling (CCS or CAS). We recommend that you use the default setting unless you require changes because of network performance. If you choose to change the signaling, use the following guidelines: For CCS signaling, the packet size must be divisible by the number of timeslots in case of E1-CCS and T1- signal - OFF. For CAS signaling, use the following formula: packet size = number-of-slots * frames-per-packet + signaling-size where signaling-size = number-of-slots/2 + number-of-slots%2 frames-per-packet for E1 = 16 frames-per-packet for T1 = 24	Enter a packet size.
Service Type	Specifies the ToS byte to be used in the IP headers of packets sent from the CTP device to the IP network. For a mapping of ToS byte values to DSCP classes and settings, see Providing QoS for CTP Bundles by Using Service Type Overview. You do not need to set the ToS value to the same value on local and remote bundles.	Enter a number from 0 through 255.
Time to Live	Specifies the maximum number of router hops that a packet can traverse. The CTP device sets the TTL value in IP packets that it sends to the IP network. Based on the TTL setting, the IP network does not alter or optimize the packet routing. You do not need to set the same TTL value on local and remote ports.	Enter a number from 0 through 255.
Source UDP Port	Specifies the source UDP port. The source UDP port is used as the circuit identifier; you must configure both circuit endpoints to use the same UDP port. The UDP port must be unique on the CTP device. You will not be able to activate a port if another port is using the same source UDP port number.	Enter a number from 1 through 65535.
Hairpin Rem UDP port	A hairpin bundle allows the creation of a pair of CESoPSN bundles on the same port or different ports with the IP address of the node as remote IP.	Enter the source UDP port number of the remote CESoPSN hairpin bundle on the same CTP2000 device. A value of ’0’ implies that this bundle is not configured as a hairpin bundle.
Max Buffer	Specifies the maximum buffer size. The maximum buffer size setting is based on the number of packets in the buffer and the number of milliseconds that it takes the packets to go through the buffer. For example, a setting of 10 ms with a packet equivalent of 2 means that it will take 10 ms for 2 packets to go through the buffer. The CTP software calculates a default buffer size based on the type of interface (T1 or E1), and the type of signaling (CCS or CAS). We recommend that you use the default setting unless you require changes because of network performance.	Enter the number of milliseconds. The number that you can enter varies depending on the type of interface and signaling. When you enter a number, the software adjusts the number to the closest acceptable number, and it displays the packet equivalent. When you enter the number of milliseconds, the software displays the packet equivalent, which is the number of packets that can go through the buffer within the number of milliseconds.
Buffer Set	Specifies the buffer size when the circuit enters a running state. The CTP software calculates a default setting based on the type of interface (T1 or E1) the type of signaling (CCS or CAS), and the packet size. We recommend that you use the default setting unless you require changes because of network performance.	Enter the number of milliseconds. The number must be divisible by the packet size. If you enter a number that is not divisible by the packet size, the software changes the setting to the closest number that is divisible by the packet size. When you enter the number of milliseconds, the software displays the packet equivalent, which is the number of packets that can go through the buffer within the number of milliseconds.
Bundle Description	Specifies identifying information about the bundle.	Type a description for the bundle.
Signal Disable	Disables or enables signalling at the bundle level for T1/E1 ports.	Select one: Yes No
